<p>perltw - 正體中文 Perl 指南</p>

<h1 id="DESCRIPTION"><a class="permalink" href="perltw.html#DESCRIPTION">#</a>DESCRIPTION</h1>

<p>歡迎來到 Perl 的天地!</p>

<p>從 5.8.0 版開始, Perl 具備了完善的 Unicode (萬國碼) 支援, 也連帶支援了許多拉丁語系以外的編碼方式; CJK (中日韓) 便是其中的一部份. Unicode 是國際性的標準, 試圖涵蓋世界上所有的字符: 西方世界, 東方世界, 以及兩者間的一切 (希臘文, 敘利亞文, 阿拉伯文, 希伯來文, 印度文, 印地安文, 等等). 它也容納了多種作業系統與平臺 (如 PC 及麥金塔).</p>

<p>Perl 本身以 Unicode 進行操作. 這表示 Perl 內部的字串資料可用 Unicode 表示; Perl 的函式與算符 (例如正規表示式比對) 也能對 Unicode 進行操作. 在輸入及輸出時, 為了處理以 Unicode 之前的編碼方式儲存的資料, Perl 提供了 Encode 這個模組, 可以讓你輕易地讀取及寫入舊有的編碼資料.</p>

<p>Encode 延伸模組支援下列正體中文的編碼方式 (&#39;big5&#39; 表示 &#39;big5-eten&#39;):</p>

<pre><code class="plaintext">big5-eten	Big5 編碼 (含倚天延伸字形)
big5-hkscs	Big5 + 香港外字集, 2001 年版
cp950	字碼頁 950 (Big5 + 微軟添加的字符)</code></pre>

<p>舉例來說, 將 Big5 編碼的檔案轉成 Unicode, 祗需鍵入下列指令:</p>

<pre><code>perl -MEncode -pe &#39;$_= encode( utf8 =&gt; decode( big5 =&gt; $_ ) )&#39; \
  &lt; file.big5 &gt; file.utf8</code></pre>

<p>Perl 也內附了 &quot;piconv&quot;, 一支完全以 Perl 寫成的字符轉換工具程式, 用法如下:</p>

<pre><code class="plaintext">piconv -f big5 -t utf8 &lt; file.big5 &gt; file.utf8
piconv -f utf8 -t big5 &lt; file.utf8 &gt; file.big5</code></pre>

<p>另外，若程式碼本身以 utf8 編碼儲存，配合使用 utf8 模組，可讓程式碼中字串以及其運 算皆以字符為單位，而不以位元為單位，如下所示：</p>

<pre><code>#!/usr/bin/env perl
use utf8;
print length(&quot;駱駝&quot;);	     #  2 (不是 6)
print index(&quot;諄諄教誨&quot;, &quot;教誨&quot;); #  2 (從 0 起算第 2 個字符)</code></pre>

<h2 id="額外的中文編碼"><a class="permalink" href="perltw.html#%E9%A1%8D%E5%A4%96%E7%9A%84%E4%B8%AD%E6%96%87%E7%B7%A8%E7%A2%BC">#</a><a id=""></a>額外的中文編碼</h2>

<p>如果需要更多的中文編碼, 可以從 CPAN (<a href="https://www.cpan.org/">https://www.cpan.org/</a>) 下載 Encode::HanExtra 模組. 它目前提供下列編碼方式:</p>

<pre><code class="plaintext">cccii	1980 年文建會的中文資訊交換碼
euc-tw	Unix 延伸字符集, 包含 CNS11643 平面 1-7
big5plus	中文數位化技術推廣基金會的 Big5+
big5ext	中文數位化技術推廣基金會的 Big5e</code></pre>

<p>另外, Encode::HanConvert 模組則提供了簡繁轉換用的兩種編碼:</p>

<pre><code class="plaintext">big5-simp	Big5 正體中文與 Unicode 簡體中文互轉
gbk-trad	GBK 簡體中文與 Unicode 正體中文互轉</code></pre>

<p>若想在 GBK 與 Big5 之間互轉, 請參考該模組內附的 b2g.pl 與 g2b.pl 兩支程式, 或在程式內使用下列寫法:</p>

<pre><code>use Encode::HanConvert;
$euc_cn = big5_to_gb($big5); # 從 Big5 轉為 GBK
$big5 = gb_to_big5($euc_cn); # 從 GBK 轉為 Big5</code></pre>
